Well if you can't remember one of the biggest dick moves Dale pulled, that might be why you look at him so favourably. Man literally did not care if Jacqui died, but then, Jacqui's not the one he had an interest in.

Maybe or maybe not. Nobody's perfect. Again, in a time of crisis, people tend to focus on their friends over strangers.

Someone assuming a guardian role of an adult with whom you have no relationship with (but may desire one) is not just something that sounds pretty selfish, it's not something you find in any realtionship. It's why the comparisons to Rick and Lori and Daryl and Carol don't wash - those are relationships which both parties entered into willingly. Dale pushed himself on Andrea.

And again, this happens all the time with people who are suicidal or otherwise self-destructive. You've got to keep pushing until you get through to them. I'm surprised you're not aware of something so basic.
